摘要:
随着高新技术产业项目的落地，西安某电子工业聚集区污水处理需求与排放标准面临双重升级压力。针对一期工程处理能力不足、电子废水进水水质浓度低且出水标准严苛（地表水准Ⅳ类）的问题，西安某工业污水处理厂开展二期扩建工程，设计规模5.0万 m3/d，采用“预处理+Bardenpho五段可调生物池+高速气浮+转盘滤池+臭氧/次氯酸钠消毒兼接触强化氧化”工艺。通过生物池Bardenpho与A2/O工艺的灵活切换、消毒池兼具接触氧化功能以及智能加药系统，实现高效脱氮除磷，并具备较强的抗冲击负荷能力。运行数据显示，出水COD、TN、NH3-N、TP稳定低于15、10、1.0和0.15 mg/L，单位处理成本低至0.78元/m3。单位碳排放仅为0.474 kgCO2-eq/m3，其中，间接排放占比78.9%，较一期工程降低10.7%，可为黄河流域电子工业园污水处理厂“高标准、低碳化”提标改造提供可复制范本。
Abstract:
With the implementation of high tech industrial projects, a wastewater treatment plant in an electronics intensive zone in Xi’an is facing dual pressures of increasing treatment demand and stricter discharge standards. To address the insufficient capacity of the phase Ⅰ project, as well as the low influent concentration of electronic wastewater and the stringent effluent requirements (surface water quasi-class Ⅳ standards), the wastewater treatment plant launched a phase Ⅱ expansion project. The expansion has a design capacity of 5.0×104 m3/d and the process adopted is “pretreatment+Bardenpho five stage adjustable biological tank+high speed air flotation+rotary disc filter+ozone/sodium hypochlorite disinfection with enhanced contact oxidation”. By enabling flexible switching between Bardenpho and A2/O modes in the biological tank, utilizing the disinfection tank for simultaneous contact oxidation, and adopting an intelligent dosing system, the project achieves efficient nitrogen and phosphorus removal while maintaining strong resistance to shock loads. Operational data show that effluent COD, TN, NH3-N, and TP are consistently below 15 mg/L, 10 mg/L, 1.0 mg/L, and 0.15 mg/L, respectively. The unit treatment cost is only 0.78 CNY/m3, and the unit carbon emission is merely 0.474 kgCO2-eq/m3. Indirect carbon emissions account for 78.9% of the total, representing a 10.7% reduction compared to the phase Ⅰ project. This case provides a replicable model for “high standard, low carbon” upgrading of wastewater treatment plants in electronic industrial parks along the Yellow River basin.
